Picture this: You’ve had a long day at work. You’re tired, you had to scrape the ice off your windshield and traffic was terrible. You finally pull into the driveway 45 minutes later than normal. You trudge through the snow, unlock the front door, walk in and all of a sudden, Jake, your 2-year old golden retriever jumps up, knocks you down and showers you with kisses and a wagging tail, happy you’re home. Instantly, your bad day is forgotten.
